Abstract: In this paper,based on the study of mineralogy,a systematic mineralogical study of metallic sulfide ores and their oxidation products from Gaobanhe lead-zinc-pyrite deposit in Hebei under room temperature conditions was carried out by using X-ray diffraction,scanning electron microscopy and other testing methods.The results show that the primary mineral assemblage is pyrite,galena,sphalerite,calcite and dolomite,etc.,and the secondary minerals are szomolnokite,roemerite,rozenite,lishizhenite,jarosite,anglesite,gunningite,gypsum and anhydrite,etc.,and the secondary mineral assemblages are different after the oxidation of the inner and outer layers of the ore.The final pro-ducts of Gaobanhe lead-zinc-pyrite deposit metal sulfide oxidation are corresponding iron vitriol minerals without forming hydroxides,indicating that the ore was oxidized in an acidic environment.Pyrite first oxidizes to rozenite and szomolnokite containing low-valent iron,and gradually forms roemerite with high-valent iron as the oxidation degree deepens.Sphalerite is easy to form lishizhenite in acidic environment enriched with high-valent iron and sulfate ion.Galena oxidation product is anglesite.The results reveal the oxidation mechanism of metal sulfide at room temperature and provide basic data for mine environmental pollution.
